DRAG.

Specification of Letters Patent.

Patented July 2, 1912.

Application filed September 8, 1910. Serial No. 580,959.

To all whom it may concern:

Be it known that I, MARSHALL J. HILL, a subject of the King of England,but having declared my intention of becoming a citizen of the UnitedStates, residing at St. Joseph, in the county of St. Croix and State ofWisconsin, have invented certain new and useful Improvements in Drags;and Ido declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to improvements in drags. v

One object of the invention is to provide a drag adapted to be attachedto any kind of a drill or broadcast seeding machine whereby the seedwill be efiectually covered.

Another object is to provide a drag of this character havingindependently pivoted teeth which are adapted to swing up when broughtinto engagement with obstacles, thereby preventing the breaking orbending of the teeth and having means whereby the teeth are yieldinglyheld down in operative position.

A further object is to provide means whereby the teeth may besimultaneously raised when desired.

WVith the foregoing and other objects in view, the invention consists incertain novel features of construction, combination and arrangement ofparts as will be more fully described and claimed.

In the accompanying drawings; Figure 1 is a side view of a dragconstructed in accordance with the invention showing the same attachedto a drill; Fig. 2 is a rear view of the same; Fig. 3 is a plan view ofthe drag; Fig. 4 is a vertical longitudinal sectional View thereof; Fig.5 is a similar view showing the teeth in raised position.

In the embodiment of the invention I provide a tooth supporting board 1which may be engaged directly with the ground when drawn over the sameor which may be provided on its opposite ends with suitable supportingshoes or as shown in the drawings said board may be supported upon smallwheels 2 which are revolubly mounted on the opposite ends thereof. Onthe board 1 near the forward edge thereof is arranged a series of shaftsupporting lugs 3 of which there may be any suitable number, said lugsbeing arranged at suitable intervals as shown. In the lugs 3 is mounteda tooth carrying rod or shaft 4 on'which is pivotally mounted a seriesof rearwardly projecting L-shaped drag teeth 5, the free ends of thelong arms of said teeth being pivotally connected with and spaced aparton the rod or shaft 4 by a series of spacing sleeves 6. The teeth 5 arepreferably of different lengths, the shorter teeth being arrangedalternately or between the longer teeth as shown. The teeth 5 project asuitable distance beyond the rear edge of the board 1 and are held downin yielding engagement with the ground by a pressure bar 7 which isloosely engaged near its opposite ends with guide pins 8 having on theirupper end suitable heads 9 between which and the bar 7 are arrangedcoiled springs 10 the pressure of which is exerted on the bar 7 to causethe latter to hold the teeth down in the manner described. By thusholding the teeth any of the same, if brought into engagement with anobstruction of any kind will be permitted to spring upwardly thuspreventing the tooth from being broken and whereupon after theobstruction has been passed the tooth will be again forced down to anoperative position.

Beyond the outer edge of the board 1 is arranged a teeth lifting bar 11,said bar being hinged to the board 1 by rigid arms 12, extendinglaterally from the inner front edge of said bar and pivotally connectedat their free ends to apertured ears or lugs 12' projecting upwardlyfrom the board 1 preferably at points midway the width thereof. Thesearms afford an extended leverage for the bar 7 when it is raised to liftthe teeth 5 under which said bar ext-ends and when said bar is swungupwardly all of the teeth will be raised to the desired elevation. Inorder to swing the board 11 upwardly and thus raise the teeth, I providea suitable lifting lever 13, which is pivotally mounted on the board 1in any sultable manner and is connected by an operating rod 14: to thebar 11 as shown. The lever 13 is provided with a locking pawl 15 adaptedto be engaged with the teeth of a segmental rack 16 whereby when the bar11 has been swung upwardly to raise the teeth to the desired elevation,said lever will be locked, thus holding up the teeth until it is againdesired to lower them.

'The drag is provided with forwardly projecting attaching bars 17 whichare adapted to be pivotally secured to the frame of a drill or seedingmachine whereby the drag will be drawn along behind the same for thepurpose of effectually covering the seeds discharged from the machine.The drag is also provided with supporting chains 18 which are adapted tobe attached at their upper ends to the drill raising shaft 18 of themachine whereby when said shaft is operated to raise the drills thechains will 3e Wound thereby simultaneously raising the rag.

From the foregoing description taken in connection with the accompanyingdrawings, the construction and operation of the invention will bereadily understood without requiring a more extended explanation.

Having thus described my invention, what I claim is:

The combination with a seeding machine, of a drag Inovably attachedthereto, said drag comprising a supporting transversely disposed board,mounted on wheels, shaft supporting lugs projecting upwardly from saidboard, a toothed segment forming the upper end of one of the lugs, ashaft mounted in said lugs, a plurality of drag teeth independentlymounted on said shaft, guide pins projecting upwardly from thesupporting board and located adjacent the opposite ends thereof, headsforming the upperends of said pins, a bar contacting with the upperedges of the drag teeth and slidably engaged therewith, coiled springsencircling the pins and disposed between the headed ends of the same andthe bar, a lifting bar hingedly attached to the-board and adapted forcontact with the lower edges of the drag teeth,

and means connected to the lifting bar and engaging with the toothedsegment for holding the drag teeth in an adjusted position.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

MARSHALL J. HILL.
